I'm pretty sure it's not the pressure release valve - I've been out and checked this while the pressure has been dropping and no dice. I'll get the expansion vessel checked out. If this needs replacing, is it likely to be something I can do myself (given that it doesn't touch any gas - is it...

Bump for the more accurate thread title! MohThoM

Just a quick addition; after raising the pressure to just under 2 bar (its former normal operating range was 2-2.25 bar) to get some hot water (without a problem!) the gauge showed 2.15 (ish) after hot water delivery. Also, likely to be completely unrelated, a cold tap in the bathroom that...

I've got a problem with my boiler, a Ferroli Optima 701, in that it will work just fine for an hour or two, but as soon as it's turned off the pressure fairly quickly drops to zero. After this I have to feed in water using the isolator, and the pressure stays in the system until the next time...
